corrons'onorrnitf I To all whom it may concern -Be it known that I, I-IAx woon G. Dn'WEv, a citizen of the United States, resldlng at yWestminster, in the j county'of Carroll and State of Maryland, have invented certain new and useful Improvements in Cotton: Choppers, of which the following is a spec My invention relates to improvements in; agricultural machinery adapted to be used as a cotton chopper, and icultlvator, while i not-necessarily restricted to this use.v

An important object of the inventioni is to provide a cotton chopper having means. for vertically adjusting the rotatable cutter and for supporting the same in such adj use ment, during thecutting operation. I

A further object of .therinvention is to provide means for chopping out the cotton, cultivating the same, and packlng or firming the row.

A further object of. the invention isto provide a machine of theabove'mentioned.

ranged upon opposite sides of the wall of the slotted guide. The upper end of the guide 43 is bolted or otherwise detachably and rigidly connected with'the transverse bar 15, as shown; The bearing 42 is raised andlowered by means of a link 44', pivotally connected with-the free end of a crank 45, which is rigidly mounted upon a rockshaft 46. Thisrock-shaft is journaled within bearings 47 secured upon the frame 10." The rock-shaft 46 is turned by the means of a lever 48, having a latch mechanism49 engaging a stationary quadrant 50.

Rigidly mounted upon the shaft 37 (see Fig. 1), is a cutter mechanism designated as a whole by the numeral 51. This cutter mechanism comprises a hub 52 which is rigidly and detachably mounted upon the shaft 37 and carries tubular arms 58. lar arms receive radial rods 59, clamped therein by bolts 60. Cutter blades 61 are rigidly secured upon the rods 59 and are adapted to be suitably angularly adjusted.

Arranged: between' the chill engaging wheels v21 and the rotatable cutter are cultivator blades 61', carried by standards 62,

detacha'bly clamped toa bar 63, carried by the frame, as shown. The wheels 21 are in longitudinal alinement with the cultivator blades 61.

Secured to the forward end of the frame 10 is a clevis or attaching devicer69, for connection with draft mechanism.

In the operation of the machine as a cot- These tubuton chopper, cultivator, and packer or former, as the same is drawn longitudinally of the hills of cotton, the supporting wheels 21 contact with the oppositely arranged inclined sides of the hill and maintain the rotating cutting mechanism 51 at the desired elevation. The vertical position of the cutting mechanism may be permanently adjusted by manipulation of the lever 48, as is obvious. The cutting mechanism receives its rotation from the wheels 13 through the medium of the intermediate gearing, and revolves in the well known manner for cutting out the cotton at spaced intervals. The cultivator blades 61 cultivate the chopped cotton, and the wheels 21 firm or pack the plowed rows.

It is to be understood that the forms of my invention herewith shown and described are to be taken as preferred examples of the same, and that various changes in the shape, size, and arrangement of parts may be resorted to without departing from the spirit of the invention or the scope of the subjoined claim.

Having thus described my invention, I claim In a machine of the character described, a frame, traction wheels secured to the frame near its forward end for supporting such forward end of the machine, a longitudinal driving shaft receiving rotation from the traction wheels, a rotatable chopper carried by the rear end of the driving shaft, a transverse bar secured to the frame and arranged near and rearwardly of the rotatable chopper, cultivator blades secured to the bar and disposed rearwardly of the rotatable chopper to act upon the sides of the hill, bevel gage wheels secured to the frame and arranged rearwardly of and near the cultivator blades in longitudinal alinement therewith, and means to raise and lower the driving shaft.

In testimony whereof I aflix my signature in presence of two witnesses.
